Total Eclipse of the Moon

On July 27 evening (Universal Time, UT), there is the total eclipse of the Moon. Exact times of four contacts (when the partial eclipse begins/ends and the total eclipse begins/ends) as well as the time interval for the total eclipse duration depend on your longitude and latitude, so, please, check the information at your local astronomical authority (e.g., local observatory, Internet). The whole eclipse is observable from India to Ukraine; its beginning only is observable form Australia and eastern Asia; and its end is observable from Europa, western Africa and South America.

Mars Observation: Great perihelic opposition 2018

On July 27, the planet Mars is AT OPPOSITION, i.e., on the line Sun-Earth-Mars, and the planet rises when the Sun gets down. It means that Mars is over the horizon through whole night. Its angular diameter is 24.3 arc-seconds and it is a very bright object of (-2.8) mag in the constellation Capricornus. Unfortunately, due to its southern declination of (-25) deg it is quite low over horizon for observers on the northern hemisphere. There is the spring on the southern hemisphere of Mars, and the autumn on its northern hemisphere.
